I don't want it to ever complain about permissions or ask for sudo password ever again. Is there any way to do this?


I have to say it is a really bad idea since it removes a big part of the security. To remove password prompts for commands/apps using sudo do

sudo visudo

to open the sudo file. Once in there change:

%sudo   ALL=(ALL:ALL) ALL



Then exit and save using Ctrl+x, y, Enter

To remove password prompts for some graphical applications that use policy kit, not sudo do the following: create a .pkla file in


for example the file could be named 99-nopassword.pkla and the path would be


That file should contain:

[No password prompt]
See the pklocalauthority manpage for more information.


To completely remove the necessity of sudo for a terminal session, type sudo -i to execute your shell. After that you don't have to run sudo until you close that session


How to disable the password prompts?

Disable authentication prompts in 15.04?

  • Thanks for answering. What about permissions though? If I do this, can I install anything without it complaining about permissions? – Val9265 Jul 1 '17 at 9:52

    You still have to write sudo but it wont ask for a password. To completely remove sudo you'd have to switch to root user by typing su root but that's an idea even worse. If you know you have to type many commands in the terminal and don't want to write sudo every time you can also execute sudo /bin/bash to open an administrator shell in which you won't need sudo. – ADDB Jul 1 '17 at 9:55
  • @Val9265 it's good idea to accept that answer if it solved your problem – Sumeet Deshmukh Jul 1 '17 at 13:17
  • @ADDB sudo -i gives a root login shell, right? Why use sudo /bin/bash then? – takatakatek Jul 1 '17 at 14:03

    @takatakatek there's a slight different, that makes sudo -i preferable to sudo /bin/bash, because sudo -i runs the specific shell of the user's password entry, while sudo /bin/bash is only for that one shell. – ADDB Jul 1 '17 at 14:09
